The Dutchman was in terrible form as Southampton won 6-1 at St Mary's.
The Saints came out of the traps on fire against Villa, scoring five goals in the first-half, with Sadio Mane scoring the Premier League's fastest hat-trick in the process.
The Senegalese forward was in top form throughout, but his job was made easy by an almost anonymous performance from the Aston Villa defence.
The main culprit getting the blame on Twitter appears to be Ron Vlaar.
The Dutch international is out of contract in the summer and has been linked to clubs such as Manchester United. After his fantastic performances for the Netherlands at the World Cup in Brazil last summer, those links were justified.
But he was woeful today.
He was constantly caught out of position and flat-heeled as the Southampton defence ran beyond him throughout.
Jores Okore was not much better, but the Dane is still young and learning, Vlaar has no excuse for his abject performance.
Judging by the reaction his performance received on Twitter from the majority of Aston Villa fans, most won't mind if he does leave when his contract comes to an end...

I think free is still too expensive for Vlaar— Ginge (@DeanoB24) May 16, 2015
Vlaar should be released.— AVFC Transfer Tweet (@AVFCTransTweet) May 16, 2015
I hope people who think Ron Vlaar is good are watching this game #dontbefooledbytheworldcup— Matt Law (@Matt_Law_DT) May 16, 2015
Vlaar's stock must have come full circle the last 12 months. At this rate he'll be begging #avfc for a new deal.— Brendan McLoughlin (@bren_mcloughlin) May 16, 2015
Has Paul Lambert come back to Villa? Awful display especially Okore and Vlaar #avfc— Carl Arrowsmith (@Carlos_1982) May 16, 2015
Recently Vlaar has changed his mind and wants to stay!? If I was Sherwood he'd be first on my list to replace. Awful mostly this season.— Marc Atkins (@djmarcatkins) May 16, 2015
